Built by a mysterious German engineer in an inhospitable location, the structure contains strange and suspicious tunnels, bunkers and more. Was this a secret Nazi base for Uboat resupply, or were there darker purposes for the house?
The 'Blockhaus' (bunker) of Éperlecques, named after a forest near Watten, in northern France near the Channel but off the coast, was a Nazi super-bunker built under the code name Kraftwerk (power plant) Nord West. Its location didn't fit the Atlantic wall, yet Organisation Todt gave it extreme priority on Hitler's persistent orders, using almost unlimited building material and slave labor. The Alies utterly ignored its purpose, yet were convinced it was no decoy but worth bombing at all cost, so they did, and the Germans kept rebuilding, even inventing novel safer techniques to do so. Ultimately they abandoned the site except as an elaborate decoy for a similar, hidden bunker nearby. It was designed as launch and final construction site for the super-weapon V2, a state of the art guided missile which luckily for England came too late to crush it, and had been less easy to counter if Hitler had followed Arms Minister Speer's advise to use mobile launch platforms on rails instead.
